Aug 09, 2016· Cliffs to unveil 'Mustang' pellet project at UTac ... iron ore of different specifications. Electric arc furnaces use nearly pure iron. Olderstyle blast furnaces use taconite pellets, which are about 65 percent iron, mixed with limestone to aid the steelmaking process and small amounts of bentonite to bond the pellet together. The iron ...

First, in the blast furnace, mined iron ore is combined. with limestone and coke to form molten iron. The purpose of a blast furnace is to chemically reduce and. physically convert iron oxides into liquid iron called "hot metal" (Blast Furnace, 2016).

•Iron ore pellets are used for the production of hot metal in blast furnaces and DRI/HBI in direct reduction processes. •A blast furnace is a shaft furnace, which is charged with iron bearing materials (pellets, sinters and/or lump ore), reducing agents (metallurgical coke) and additives (limestone, quartz, BOF slag).

Indian iron ore fines with high alumina content (~% Al 2 O 3 ) resulted in poor quality pellets and a study was under taken to establish suitable pellet chemistry through proper fluxing agents. Limestone fluxed pellets were prepared at varying basicity (0 to ) and pyroxenite fluxed pellets at varying MgO contents (0 to 3%) to study their effect on the metallurgical properties.

Iron ore pelletizing These are typically fed to a blast furnace or DRI plant as part of the process to make steel Iron Ore Pellets are formed from beneficiated or run of mine iron fin mixed with limestone or dolomite as a fluxing agent and bentonite or organic

In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it can be utilized, as opposed to disposed of. The Pelletizing Process. The production of iron ore pellets .

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

Pellets for metallisation made from an upgraded concentrate have at least 66% Fe and are used primarily to produce direct reduction iron (DRI, HBI). Iron ore pellets are produced from the iron ore concentrate by pelletizing and sintering and are used as the feedstock for the blast furnace process.

So after the pelletizing and screening operations, iron ore pellets have to be hardened in a furnace through a firing process. Once fired, they can be handled, loaded in ships or trains and delivered to the end users. Two indurating furnace technologies dominate the pelletizing industry,...
